Why do Manhattans have to be so frickin' great?

Just finished off a bottle of WT Rye with the following:

2.5 oz. rye
.5 oz. sweet vermouth
2 dashes angostura bitters

Good thing I limit myself to weekends for making Manhattans, because if I had one every night, I'd keep going w/2 or 3 more. In other words, I'm a Wednesday night Manhattan away from being a full-blown alcoholic.
